The Conservation Team Turn Detective!

on Friday, 22 May 2015. Posted in Conservation

Finding the cause of deterioration in a pair of Imari vases. A serial conservation mystery, episode 1

In the conservation lab we have two very large and impressive-looking vases. The vases from Wilton House, Salisbury have come to the conservation lab to be repaired as they are both structurally unstable. The conservation team turned detective in order to discover what was causing the instability. In the first episode of our conservation blog, you’ll find out how the conservators uncovered the symptoms and solved the case.

The patients

The vases are late 17th Century examples of the popular Japanese style ‘Imari’ identified from the distinctive decoration of cobalt blue under-glaze and gold and red over-glaze. This style of Japanese porcelain was produced as export for the Western market, indicated by the style sharing its name with the Japanese port from which it was transported: Imari, Saga.

The symptoms

The vases have large cracks running from the base, nearly ¾ of the way up the sides. The cracks weaken the structure and cause the significant instability. Along the edges of the cracks and round the base of the vases are missing areas of decoration and glazing. As the vases are no longer in one piece, they are not safe to display in this condition. While the cracks remain, these vases continue to be at risk of breaking apart.

 

The suspects

Although the symptoms of deterioration could be clearly identified, their cause remained a complete mystery. The conservation team could treat the symptoms. We could fill the large cracks and repair the glazing but without discovering the cause of the damage and finding a suspect, we would be taking a big risk. Further deterioration could occur in the future and the vases become irrevocably damaged.

Celebrating the 8OOth anniversary of the Magna Carta

on Monday, 16 March 2015. Posted in Conservation

The Wiltshire and Swindon History Centre have been preparing an up-coming display to mark the 800th anniversary of the Magna Carta, which is to be held at Lacock Abbey.

The display will feature three original documents: a facsimile of the 1225 Magna Carta presented to Lacock abbey after the original charter was presented to the nation; and two enrolled copies of a 1300 confirmation of the charter in the archives of the marquis of Ailesbury of Savernake and Marlborough borough which are held at the Wiltshire and Swindon History Centre.

These documents will be supported by a display illustrating life in Wiltshire in the 13th century and the impact of Magna Carta. Copies of documents will include images from the pageant in 1932 to celebrate the 800th anniversary of the founding of Lacock abbey.

The exhibition will be at Lacock Abbey in June and July and then at the Wiltshire and Swindon History Centre. The screens will then be available for display around the county.

A project to conserve and display 13th Century documents for the Salisbury Cathedral Magna Carta exhibition.

The Archive conservation team have recently been working on a project to conserve and display four 13th Century parchment documents for the 800th Anniversary of the Magna Carta exhibition at Salisbury Cathedral.

The documents are: a charter, an indulgence, a declaration of canonical obedience and an agreement of tithes.

Parian Ware - A Complex Jigsaw

on Tuesday, 06 January 2015. Posted in Conservation

We recently had a number of Parian ware figurines come in for treatment. Parian ware is a type of unglazed porcelain used in the 19th century to imitate marble. It was usually used to make figurines and other decorative pieces.  

The damage on the pieces ranged from a few minor chips to items that were in a fragmentary condition. It was clear that this would be a challenging treatment. Piecing together the broken items was especially difficult as fragments from many different figures were present in each box. It was not clear until we started work which object some of the fragments belonged with. Each piece would need to be positioned precisely to allow the fragments around it to fit correctly. Some joins had to be taken down and re assembled several times before the rest of the object could be put together satisfactorily.

Our Conservation team's expert handiwork is now on display at the Museum of East Asian Art

on Tuesday, 05 August 2014. Posted in Conservation

The Museum of East Asian Art in Bath currently has an exhibition showcasing some of their exquisite Chinese Metalwork and the conservation work carried out on the objects by conservators here at the Wiltshire and Swindon History Centre. The aim of the exhibition is to show that by carefully cleaning and looking after objects we can ensure they will be treasured for generations to come.

The objects on display are highly decorated often involving the use of, gold and silver or other coatings such as lacquer and enamelling. The presence of additional materials and decorative coatings makes the conservation of such objects more complex and so poses more of a challenge. Each of the treatments needs to be picked carefully to ensure the work carried out on one of the materials does not adversely affect any of the others.

How can I get a career in heritage?

on Friday, 20 June 2014. Posted in Archives

Here at the Wiltshire and Swindon History Centre we often get requests for work experience by people interested in a career in heritage, so it seems timely, with the end of the school year approaching, to run through some key facts and provide some useful links. This guidance is primarily aimed at those living in England - other parts of the UK may need to use a search engine to find links more appropriate to them.


The first thing to note is that ‘heritage’ is a very broad term and you will need to decide which aspect of it you are most interested in, as there is specialist vocational training for different careers and you can save yourself a lot of time and money by investing in the right training sooner rather than later. (For example if you want to become a qualified archivist it is essential to have a degree plus a post-graduate qualification in an accredited topic such as Archives Management – you cannot simply have a history degree, or an MA in another topic, even if it’s heritage-based.)

Life in the Navy

on Tuesday, 03 June 2014. Posted in Military

Among the papers of the Jeffrey family deposited in the Wiltshire & Swindon Archives, (Ref:1369/16) are a remarkable collection of letters to and from John Russell, a man probably best described as an 18th century equivalent to Samuel Pepys.

Working in the first half of that century, Russell became Clerk to the Navy at Deptford from 1730, having already spent much time at sea and went on to become Consul General in Lisbon in 1749.


The letters offer a wonderful insight into naval life during this period and often refer to ‘celebrities’ of the time. Beau Brummel, for instance, gets a mention in one letter. Archivists at the History Centre believe this collection has a national importance.


Unfortunately, the ravages of time, mould and mice have taken their toll leaving the letters extremely weak and fragile and requiring conservation.

The Archive Conservation staff have an on-going programme of repair and another folder of 50 letters (they number hundreds in total), is nearing completion. Because of their precarious condition full, traditional repair has been carried out involving backing, endorsements and infilling. This will prevent further damage and at last make them accessible to researchers.
